i just thought for a second and realized that if you use fortitude lute on movement 4 da capo, da capo will have 85% defence, to put that into perspective, da capo with 60% defence has an effective hp of 350 (with base hp of 140), however, with 85% defence, da capo has 933 effective hp, which while crazy enough, if you have base hp of 165 (for example if you have the melee kit in tc) and 85% defence, you have 1100 effective hp, which allows you to survive AMERICA (asuming you dont die to knockback), but wait, there is more, if you pick tank kit, you have 250 hp, and if you get 85% defence, you have a crazy 1933 effective hp, which makes you basicly invincible. so remember, if you got da capo on your team and you have lute, pick fortitude, and you will win.
Once a capo gets movement 2 or 3 they are unstoppable (unless death note America or pact) since it converts aura dmg to hp (basically every dmg you do to an enemy you regenerate lost hp)
People who manage to sweep the game using da capo or smile are the luckiest people because i merged with smile 6 times before and got 2nd movement with da capo 3 times but 80% of the time i always got death noted or ended or tsar bombed in like 30 seconds after i activate the trumpet
i once had 2 da capo's. 1 smile and a bird up on my team (the da capo's got movement 4 and lasted for almost the entire round. the smile merged to third trumpet. and the bird up lasted the whole round. i wasn't any of them but i had birch tree AND skeleton juice to feed my team)
